Electronic Navigation (ENAV)

Course Description

This course is required for all Able Seamen upgrading to 3rd Mate/2nd Mate. It covers the theory and practical use of electronic navigational aids. This course provides knowledge and understanding of the electronic navigational aids that trainees will find aboard a ship. The trainee will learn the basic principles of the systems, advantages, disadvantages, accuracy, and various errors of each.

This course satisfies the following STCW95 and CFR training requirements:

• STCW95 Table A-II/1
• IMO Reference 7.03 
• 46 CFR 11.901(c)(1)(iv)  Formerly 46 CFR 10.901(c)(1)(iv)
• 46 CFR 11.901(c)(1)(v) Formerly 46 CFR 10.901(c)(1)(v)

Prerequisites-Radar Unlimited (5-day certified course). This course is offered at MITAGS onsite.
